   * Creates a new shortcut (.lnk) file. This shortcut will be recorded in
   * a new shortcuts log file located in %PROGRAMDATA%\Mozilla-1de4eec8-1241-4177-a864-e594e8d1fb38
   * that is named after the currently running application and current user, eg:
   * Firefox_user123_shortcuts.ini.
   *
   * For reasons that we haven't been able to pin down, these shortcuts get created with
   * extra metadata on them (KnownFolderDataBlock, SpecialFolderDataBlock) that cause
   * the Windows ShellLink classes to improperly read their target path with certain
   * parameters. This causes any 32-bit programs that read the links (such as our
   * installer and uninstaller) to think that 64-bit installs are located in the 32-bit
   * Program Files directory.
   * See https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/6f2e7920-50a9-459d-bfdd-316e459e87c0/ishelllink-getpath-returns-wrong-folder-for-64-bit-application-when-called-from-32-bit-application
   * for some additional discussion of this.
   *
   * @param aBinary Target file of the shortcut.
   * @param aArguments Arguments to set for the shortcut. May be empty.

   *        shows up as the hover text of the shortcut in Explorer and on the
   *        Taskbar (if the shortcut is pinned there).
   * @param aIconFile The file containing the desired icon for the shortcut. This
   *        can be the same file as aBinary.
   * @param aIconIndex The index of the in aIconFile. Note that this is 0 based index
   *        that IShellLinkW requires, _not_ a Resource ID that is sometimes used
   *        for icons.
   * @param aAppUserModelId The App User Model ID to set for the shortcut. This will
   *        affect which icon on the Taskbar the application groups with when first
   *        launched.
   * @param aShortcutFolder The special Windows folder to create the shortcut in. One of:
   *        CommonStartMenu, StartMenu, PublicDesktop, Desktop, or QuickLaunch.
   * @param aShortcutName The filename of the shortcut within aShortcutFolder.
   * @return The full native path to the created shortcut.
